BACKGROUND

The present invention relates to a display device.

A display device is a device which visually displays information incharacters, graphs or figures, and may be a display device such as aliquid crystal display, a plasma display, or an OLED display.

The display device may include a display panel such as a liquid crystaldisplay (LCD) or organic light emitting diodes (OLED), a front casecovering a front edge of the display panel, and a back cover protectinga rear surface of the display panel.

The display device can be classified into a wall-mounted display deviceused in a state of being hung on a wall, a stand-type display deviceused in a state of being stood on a stand, and the like, according tothe mounting manner.

The back cover supports the display panel and may be configured with acombination of a plurality of members.

In a case where the back cover is configured with a combination of aplurality of members, the rigidity of the back cover can be improved,and in particular, in a case where a portion of the plurality of membersis made of metal, the rigidity thereof can further increase.

Meanwhile, there are problems that, in a case where the rigidity of theback cover is weak, the large display device among the display devicesmay have increased warpage, and in a case where the thickness of theback cover increases to increase the rigidity of the back cover, theweight and material cost of the back cover and the display deviceincrease.

A bent portion bent to protrude in the rear direction can be formed onthe corrugated panel.

According to the embodiment of the present invention, a plurality offirst holes between the front skin and the corrugated core and aplurality of second holes between the corrugated core and the rear skincan be formed to be long in the vertical direction, respectively, sothat the deflection amount of the corrugated core can be minimized andthe corrugated panel can reliably support the display panel.

In addition, the first body of the module cover can shield the gapbetween the rear surface of the display panel and the front surface ofthe front skin, the second body of the module cover covers the rearsurface of the rear skin to prevent exposure of the rear skin, and thesecond body of the module cover can protect the rear surface of the rearskin.

In addition, the second adhesive member may be attached to the rearsurface of the OLED and the front surface of the front skin, so that theOLED can be directly fixed to the corrugated panel by the secondadhesive member.

In addition, since the corrugated core is thin, the corrugated shape canbe easily formed, and the formability is high.

In addition, the second body of the module cover can be reliably fixedto the front skin and the display panel and between the front skin andthe display panel, respectively.

In addition, since the first adhesive member and the second body areaccommodated in the recessed portions formed in the front skin, the stepbetween the front surface of the front skin and the front surface of thesecond body can be minimized, and the overall thickness of the displaydevice can be minimized than a case where the second body is positionedoutside the recessed portion.

In addition, a nut can be press-fitted into the second core and therecessed portion formed the front skin, so that it is possible tominimize the contact of a front end of the nut with the display panel.

In addition, a nut can be press-fitted into the recessed portion formedin the rear skin, so it is possible to minimize the damage of thedisplay panel due to the nut.

In a case where the corrugated panel 2′ is coupled with the stand 7 orthe PCB plate 8, the bolt passes through the bolt through-holes formedin the stand 7 or the PCB plate 8, and be fastened to the nuts N1 and N2mounted on the corrugated panel 2′.

When the bolt is fastened to the nuts N1 and N2, it is preferable thatthe nuts N1 and N2 be mounted so that the bolts do not interfere withthe display panel 1 when the bolt is completely fastened to the nuts N1and N2.

When the nuts N1 and N2 are fixed to the corrugated panel 2′, it ispreferable that the front ends of the nuts N1 and N2 be fastened so asto be spaced apart from the rear surface of the display panel 1, the nutN1 press-fitted into the inner recessed portion G2 of the front skin 21′or the nut N2 press-fitted into the rear recessed portion G3 of the rearskin 24′ can keep a state of being spaced apart from the display panel1.

Meanwhile, the corrugated panel 2′ may be formed with a bent portion 29which is bent to protrude in the rear direction.

The bent portion 29 may be a portion where the front surface of thecorrugated panel 2′ is recessed and the rear surface thereof protrudes,and the thickness thereof (that is, width in front and rear direction)may be the same portion as the peripheral portion of the bent portion29.

The bent portion 29 may include a portion of the first core 28A which isbent from the peripheral portion in the rear direction, a portion of thefront skin 21′ which is bent from the peripheral portion in the reardirection, and a portion of the rear skin 24′ which is bent from theperipheral portion in the rear direction.

The bent portion 29 is a configuration which causes the PCB 9 to becapable of being spaced apart from the periphery of the bent portion 29,the PCB 9 can be in contact with or be fastened to the bent portion 29,and a gap G4 can be formed between the periphery of the bent portion 29and the PCB 9.

The above-disclosed subject matter is to be considered illustrative, andnot restrictive, and the appended claims are intended to cover all suchmodifications, enhancements, and other embodiments, which fall withinthe scope of the present disclosure.

Thus, the embodiments of the present disclosure is to be consideredillustrative, and not restrictive.

Therefore, the scope of the claimed invention is defined not by thedetailed description of the disclosure but by the appended claims, andall differences within the scope should be construed as being includedin the appended claims.

What is claimed is:
